JDK1.2 JFC - Lightweight vs Heavyweight (or Visual Cafe problem?)

JDK1.2 JFC - Lightweight vs Heavyweight (or Visual Cafe problem?)

I am doing a GUI app for my company and have run into a problem showing/updating a progress dialog. I understand from Sun's online documentation that you should not mix heavyweight (AWT Objects) and lightweight (Swing Objects) in the same application. I am using JFC (Swing) for all of my GUI objects. I am trying to show a JProgress bar inside of my JDialog window. However, all I see is the outline of my JDialog box and the JButton inside of it. Everything else including the background is the main JApplet object and its components shows through the JDialog box. I am using Visual Cafe to build my GUI, so I don't know if this is a Visual Cafe problem or not. Can anything offer a suggestion? Thanks.

I have had the same problem working with swing, but I don't think Visual Cafe is at fault. I experienced the same problem compiling my programs outside of Visual Cafe with just the JDK.

I don't have the problem when I build a screen and wait for user input, but if I build a screen and then do some processing instead, Swing doesn't seem to feel it needs to finish painting the screen until the process finishes. I've tried calling repaint() and even paint() to no avail. I've had some success with revising the text on a displayed component while the process is continuing - in this case swing will finish repainting the previous version of the screen.

I've just recently tried JDK 1.4.0 and there is an improvement.
